I can tell by all the replies since my last post everyone is sitting on the edge of there chair waiting for my next one so here goes.
I recieved my Wunderlich tall Ergo todad for my F800 install it, and took it for a test ride. Its somewhat better than the 18" Cee Bailey both screens are about the same height but the Wunderlich stands more Vertical, thus moving the air up to above my face shield. but the air blast still hits the top of my helmet and causes buffeting (lots of noise). When I hold my head down aprox. 2" all the noise and buffrting goes away completly.
After talking with Wunderlich I understand That Germany is Working on a articulating screen extention. But they don't know when it will be available.
It looks to be easily removable for off road, so you might just be able to have your cake and eat it too. Wouldn't that be great!
Meanwhile I am going to fabricate one of my own. Till next time
